Repeat as far as White's 8th move inclusive.
Should Black play, instead of 8. ... Kt to K 2, 8. ... Kt to Kt 5, the
following variations may ensue:
{376}
9. Q to K 4 9. P to Q Kt 4
10. B to Kt 3 10. P to B 4
11. Kt takes P 11. B to R 3
12. P to Q R 4 12. R to B sq.
13. P to Q 3 13. B to K 2
14. Castles ...
White threatens now a formidable attack with 15. P to K B 4, to be followed
by attacking the Knight with the Q B P, and so to win back the piece.
... 14. B to Kt 2
15. P to Q B 3 15. P to Q R 3
If 15. ... Kt to R 3, White would win with 16. P to K B 4.
16. Q to Kt 4: ch. 16. K to B 2
17. P to K B 4 17. R to B sq. (best)
18. P takes P: dis. ch. 18. K to Kt sq.
19. B to R 6 (!) 19. R takes R: ch.
20. R takes R 20. B to B sq.
21. Kt to Q 6, and wins.
For the immediate threat, 22. Q to K 6: ch., or Kt takes B, is fatal.
